Select "Growth" or "Decay" to classify each function.

nasty-shy [4]

A) y=1/2(2.5)^t/6 is the only growth function, the other two are for decay as the multipliers in the brackets are less than 1, thus indicating decay
C) 20(1.2)^4= 41 views
D) A and C as the multipliers in the brackets are less than 1, thus indicating decay

Use properties of multiplication to show why 4 x 50 = 8 x 25.

nikdorinn [45]

Given:

$4\times 50 =8\times 25$

To find:

The steps to prove the given statement by using the properties of multiplication.

Solution:

We have,

$4\times 50 =8\times 25$

Taking left hand side, we get

$LHS=4\times 50$

$LHS=4\times (2\times 25)$

$LHS=(4\times 2)\times 25$ (Associative property of multiplication)

$LHS=8\times 25$

$LHS=RHS$

Hence proved.

Can you help me how to solve this problem ? thank you

Art [367]

Since BCDEF is regular, we know right away that $x=\dfrac{360}5=72$ because the measures of all exterior angles of any regular polygon add to 360 degrees; they are all of equal measure here, so we divide 360 by 5.

For the pentagon BCIHG, the same is true, which means we have the equation

$\underbrace{72}_x+\underbrace{72}_{\angle_{ext}BCD}+\underbrace{90}_{\angle_{ext}CIH}+\underbrace{(180-y)}_{\angle_{ext}IHG}+\underbrace{68}_{\angle_{ext}HGB}=360\implies y=122$

So $x+y=194$ .
